The Lowdown
Alright folks, Rusty here. Let’s take a proper look at what’s on offer for Kennebunk Beach over the next couple of weeks.
Honestly, I’m looking at a pretty flat spell ahead. For the first several days, from Saturday the 18th right through to Wednesday the 22nd, the surf is just not happening. The swell is barely a ripple, and when it does show a bit of size, the wind is all wrong. That Saturday afternoon on the 18th sees a jump to 6ft, but it’s from the south with a short, choppy 6-second period, and a strong onshore wind. The combined energy hits 206 (moderate), but it’s messy, blown-out stuff. Not worth your time. There’s a real gap here with no decent waves to speak of for the first five days.
Now, we finally get a glimmer on Thursday morning, the 23rd of July. The water temp is sitting at 64°, which is about normal for the time of year. We’ve got a clean 4ft swell from the SSE, with a period of 9 seconds, and a light offshore wind from the ENE. The combined energy is 252 (moderate), and the wave comment even says “clean.” That’s the best we’ll see, but it’s still only earning a 1/10 for overall quality. It’s surfable, but just barely. Kennebunk Beach is a sheltered spot, and it’s fairly consistent, but with a NE offshore wind, it can get a little tricky. Crowds are possible here.
After that, we slip back into the doldrums. Friday the 24th morning has a clean 3ft, but it’s weak. Then from the 25th right through to the end of the month, it’s a mix of tiny, weak swells with onshore winds. The energy is low, mostly under 100. There’s a moment on Monday the 27th morning with a clean 2ft and a light offshore, and again on Tuesday the 28th morning with a glassy 1ft and a 10-second period, but the height is just too small to get excited about. The swell direction is mostly from the SE, which isn’t the optimum ENE direction for this spot.
Into the first week of August, we see a tiny uptick on Friday the 31st afternoon, with a 5ft swell from the SSE, but it’s a short 5-second period, so it’s just wind chop. The energy is 98 (weak). Saturday the 1st of August has a similar story: 4ft to 3ft, but onshore winds and poor conditions. The only real standout, if you can call it that, is the Thursday morning, 23rd of July. It’s the cleanest of a very poor bunch. For the rest of the run, it’s a case of small waves and average winds. If you’re desperate for a paddle, the 23rd is your best bet, but don’t expect much.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
